This presentation shows the importance of having balanced Diet.The importance of having the combination of variety of nutrients.This presentation also describes the different dividions of food and their sources,Carbohydrates,Proteins,Fat,Vitamins and Minerals etc...

1. BALANCED DIET
BALANCED DIET

2. • Balanced diet is a combination of different
varieties of nutrients.To maintain good health and
physical efficiency the diet should contain adequate
amount of all nutrients.

3. On the basis of their pre dominant
functions foods are sometimes grouped as
• energy yielding food – carbohydrates and fat
• Body building food – protein
• Protective food – vitamins and minerals

5. • Carbohydrate contain carbon , hydrogen , and
oxygen. The main function of carbohydrate in the
body is to provide energy. The glucose formed by the
digestion of the starch and sugar is absorbed mainly
into the blood through the walls of the intestine and
carried to the live in.
• when the carbohydrate are supplied in the diet in
excess that will be converted into fat and stored as
such in the adipose tissues

6. USES• Quick source of energy
• It regulates amount of sugar circulation
in the body
• It assist in bodys absorption of calcium
• One mole of carbohydrate releases 4.1
Kcal energy
• It helps in lowering cholestrol level

7. FAT

8. • Fat is a component used in the production of
several hormones like compounds which help
to regulate blood pressure, heart rate, blood
vessel constriction, blood clotting and nervous
system

9. USES
• Delayed source of energy
• Helps to maintain body temperature
• It lubricants and smoothens the body
• One mole fat releases 9.45 kcal of energy
• Helps to maintain healthy hair, skin etc.
• It protects delicate organs against being injured

11. • Proteins are made up of amino acids. Out of 23 amino
acids, eight are essential and they cannot be manufactures
in our body and are to be supplied from outside. Proteins
are present in all living tissues both in plant and animal.
Proteins are very large organic compound , which contain
carbon , hydrogen, oxygen, nitrogen etc.

12. USES
• Fix building new tissues
• For lactation
• Maintenance of tissues already built and
replacement of regular losses
• Functions as regulatory substances for internal
water and acid base balance
• It also produces heat and energy in the absence of
carbohydrate

14. MINERALS
• Minerals provide material for the growth and
development of bones and teeth. They are also
needed for the growth of body cells, especially the
red blood cells. They are ingredients of various
body fluids and are more important for proper
functioning of the circulatory and nervous
system

15. USES
• They maintain acid balance in the body
• They regulate noral system in the heartbeat
• They regulate normality in reaction time
• Formation of bones and teeth
• It actvates the digestive system and
strengthens muscles and nerves

16. MAJOR MINERALS ITEMS

17. VITAMINS

18. VITAMINS
• Food contain certain chemical substances in
small amount called vitamins. It play a key role
in most chemical reactions in the body but they
do not provide energy . Many of the cell
reactions are carried through enzymes. It is made
by the combination of vitamins and minerals. If
one item happens to be missing that enzyme
cannot be formed and some important
functions of the body cannot be carried
out. So no one can survive without
vitamins

19. • On the basis of the characterstics
of their solubility vitamins
are categorized as
• 1. water soluble – B complex and C
• 2. Fat soluble – A D E K

20. USES
• It facilitates the digestive action
• For proper growth of the body
• It produces disease resistance and destroying
capacity
• For proper physical reproduction

22. WATER
• Water is medium in which most of the
chemical reactions connected with
metabolism and life take place . Man cannot
live without water and its best fluid to drink
in any form. 75% of the body consists of water
. An average adult need to take 2 to 3 litres of
water a day because the same amount is
eliminated from the body in the form of urine,
perspiration and water vapors in the process
of breathing

23. USES
• It helps in the elimination of poisonous
elements and waste products from the body in
the form of sweat and urine
• It helps in the digestion of food
• It regulates the body temperature
